Basic Collections

Seven values are given to you, one per line of the input, each written as a Python expression — a list, a tuple, a set or a range. Read them in this order with eval(input()):

1. int_iterable — an iterable of integers (e.g. range(1, 10, 3))
2. string_iterable — an iterable of strings (e.g. ["Apple", "Orange", "Banana"])
3. some_value — a single value (e.g. 4)
4. some_collection — an ordered collection of at least three items (e.g. [1, 2, 3, 4])
5. some_iterable, 6. another_iterable, 7. yet_another_iterable — any three iterables

Now assign each of the variables below. Nothing has to be printed; the variables themselves are graded.

Collection literals

• empty_list, empty_set, empty_tuple — an empty list, an empty set and an empty tuple. Careful: {} is an empty dict, not an empty set.
• singleton_list, singleton_set, singleton_tuple — a list, a set and a tuple holding exactly one element.
• a_falsy_list, a_falsy_set — a list and a set for which bool(...) is False.
• a_truthy_tuple — a tuple for which bool(...) is True.

Aggregating int_iterable

• int_iterable_min, int_iterable_max, int_iterable_sum, int_iterable_len — its smallest value, its largest value, the sum of its values and how many values it has.
• int_iterable_sorted — a list of its values in ascending order.
• int_iterable_sorted_desc — a list of its values in descending order.
• int_iterable_reversed — a list. If int_iterable is a list, reverse it with reversed(); other iterables are not all reversible, so in that case sort it ascending first and reverse that.

Indexing and slicing some_collection

• third_last_element — the third element from the end, but only if some_collection is a list or a tuple; otherwise None (sets are not indexable).
• odd_index_elements — the elements at the odd indices 1, 3, 5, …, keeping the type of some_collection, if it is a list, tuple or range; otherwise None.
• is_some_value_in_some_collection — True if some_value is in some_collection.
• is_some_value_in_even_indices — True if some_value appears at one of the even indices 0, 2, 4, … of some_collection, if it is a str, list or tuple; otherwise None.

Combining the rest

• all_iterables — a single list holding the items of some_iterable, then another_iterable, then yet_another_iterable.
• all_concat — the strings of string_iterable joined with - between them. If string_iterable is a list, keep its order; otherwise it is unordered, so sort the strings first.

Your task

The input is read for you. Assign the answers to empty_list, empty_set, empty_tuple, singleton_list, singleton_set, singleton_tuple, a_falsy_list, a_falsy_set, a_truthy_tuple, int_iterable_min, int_iterable_max, int_iterable_sum, int_iterable_len, int_iterable_sorted, int_iterable_sorted_desc, int_iterable_reversed, third_last_element, odd_index_elements, is_some_value_in_some_collection, is_some_value_in_even_indices, all_iterables, all_concat.

You do not need to print anything — the values you assign to those names are what gets checked, in that order.

Example

Input
